Help!!

I have a 2year old son that wont take any meds orally. He now was prescribed antibiotics for a finger infection due to an ingrown finger nail. But i cant make him take it. He starts kicking and screaming and spiting everything out even if i put it on the side of his cheek. I need help i emailed his pediatrician but she hasnt responded yet. Any advice? The antibiotic is flavored so i tried putting it mixed with danimals yogurt but he didnt like the mixture so he threw it away and refused to drink it.
